ABSTRACT:
The invention relates to a method and/or a device for determining a constellation from a plurality of possible constellations with a constellation identification device which is used to determine the constellation of the signal from a plurality of possible constellations. This is advantageously achieved when a converter is arranged to convert the signal into polar coordinates provided with a radial component, and to provide a radius as a radial component of the signal, wherein the constellation identification device is constructed so as to determine the constellation of the signal from the radius.
